@Emmerich 感谢。看来还是开 9929 性价比高一点。

开了没公网 ip 了吧

上海联通到软银 QOS 力度是不一样的，同样都是 AKARI 的机器，两个不同的网段到上海联通同一个 IP 的延迟完全不一样，低的 50 多高的 100 ，应该是联通 4837 特有的 ECMP 机制，100 多的应该是绕北京了，路由不一定能测出来

@ecapsul 开了是没有了。但是现在同运营商跨省和同省市跨运营商都有严重的 QOS ，特别是跨省和运营商两者同时叠加那速度慢的没法用，我早就是用云服务器来做 BGP 中转了。


@duoluo1234 感谢提供参考。

@fengyaochen 现在用 traceroute 和 nexttrace 应该还是准的吧，目前好像没听过运营商会去改写路由。一直没想通同一个 ip 出口处汇入的丢包率还比杭州联通绕道上海还高。

上海联通 4837 由于众所周知的原因，很多 IP 属于黑名单，结果就是每次分配到的 IP 对外的访问路由完全不可预知

@Hephaistos 我之前也用上海联通好几年才知道有这事，后悔把 9929 套餐取消了现在每月得多 20 🤣。

@coolcoffee ECMP 会分流，绕路也不一定测的出来，另外就算 ECMP 没有绕路，高延迟也有可能是因为分流到负载高的交换节点上导致延迟上升，电信联通 163 和 4837 的线路质量参差不齐，这也是为什么大家都追求 CN2 和 9929 的原因

@coolcoffee 我最近几天香港的好几台 vps 速度明显变慢。是不是和这个相关？
